COMBINATION PAPER-KNIFE AND MAIL-OPENER.

SPECIFICATION forming part of Letters Patent No. 767,647, dated August 16, 1904.

Application filed December 26, 1903. Serial No. 186,542. (No model.)

To all whom it may concern:

Be it known thatI, JOHN A. KNIGHT, a subject of the King of England, residing at Lynn, in the county of Essex and State of Massa chusetts, have invented new and useful Improvements in a Combination Paper-Knife wrappers of newspapers and the like; and,-

further, my improved device is provided with a cutting edge which may be used as aneraser, and still further with a file-surface adjacent to and extending longitudinally of one side thereof which may be used in filing the nails.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Figure 1 is a plan view of my improved paper-cutter and mail-opener. Fig. 2 is a side elevation of the same. Fig. 3 is a detail section taken on line 3 3 of Fig. 1. Fig. 4is detail section taken on line 1 4: of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 is a flat blade of metal having one side 6 sharpened to form a cutting edge to be used in the manner of an ordinary paper-knife.

7 is a file-surface formed upon the opposite edge of the blade 5 beneath the surface and extending longitudinally thereof.

8 is a pointed end, and 9 a splitting-blade turned up from one edge of said flat blade, extending longitudinally thereof and at right angles to the face thereof. The cutting edge of the blade 9 and the pointed end 8 lie in the same planeviz., a longitudinal median plane of the blade 5 at right angles to the face of said blade. A convexly-curved cutting edge 10 extends from the pointed end 8 to the right tinued movement of the same splits the wrapper along a straight line without injuring the contents of said wrapper. The curved cutter edge 10 is used in a manner well known to those skilled in the art.

The advantage secured by'my improved device is the combination in one tool of a number of convenient forms of paper-cuttingknife edges by means of which the operations hereinbefore described may be quickly and conveniently performed.

- Having thus described my invention, what i I claim, and desire by Letters Patent to secure,

1. As an article of manufacture, a papercutter comprising a flat blade, and a splittingblade turned up from one edge of said flat blade, extending longitudinally thereof and at right angles thereto.

2. As an article of manufacture, a papercutter comprising a flat blade with one end thereof pointed, and a splitting-blade turned up from one edge of said flat blade, extending longitudinally thereof, said pointed end and spliting-blade lying in a longitudinal median plane at right angles thereto.

3. As an article of manufacture, a papercutter comprising a flat blade with a cutting edge on one side thereof, with one end thereof pointed, and a splitting-blade turned up from one edge of said flat blade, extending longitudinally thereof and at right angles thereto.

4. As an article of manufacture, a papercutter comprising a flat blade with a cutting edge on one side thereof, one end thereof pointed, and a splitting-blade turned up from one In testimony whereof I have hereunto set edge of said fiat blade and extending longitumy hand in presence of tWo subscribing Witdinally thereof, said splitting-blade and pointnesses.
